Narrative:
During an instrument landing in night instrument meteorological conditions, the airplane exited the far end of the runway and struck the instrument landing system localizer antenna system. The pilot and the co-pilot both reported that, due to fog and low visibility, the pilot flared the airplane too high and landed too long on the runway. The pilot applied maximum braking and reverse thrust, but could not stop the airplane before exiting the runway. The reported weather was visibility of 3/4 mile in mist and an indefinite ceiling at 200 feet. The operator reported that there was no mechanical malfunction or failure of the airplane that would have precluded normal operation. Both pilots were likely influenced by the mission pressure to land because of medical considerations for a passenger on board.
Probable Cause: The flying pilot's failure to attain the proper touchdown point in low-visibility conditions, which resulted in a runway overrun. Contributing to the accident was mission pressure to land at that airport.
